Reference of 3250-73-5, Adding some certain compound to certain chemical reactions, such as: 3250-73-5, name is 2-(2-Ethoxyphenoxy)ethanol,molecular formula is C10H14O3, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 3250-73-5.
To a solution of (ether)benzoxy alcohol 20A (501.2 mg, 2.751 mmol) in CH2Cl2 (20 mL) was added Et3N (509 mg, 5.03 mmol) and toluenesulfonyl chloride (623 mg, 3.27 mmol) at 5-10 C. After being stirred at 25 C for 30 min, the reaction mixture was quenched with saturated aqueous Na2CO3 (20 mL) and extracted with ethyl acetate (3 × 50 mL). The combined organic layers were dried over MgSO4(s), filtered, and concentrated under reduced pressure to obtain (ether)benzoxy tosylate 21A (853.5 mg, 2.539 mmol) as white solids in 92 % yield: mp (recrystallized from CH2Cl2 and CCl4) 82-83 C; 1H NMR (CDCl3, 300 MHz) delta 1.43 (t, J = 10.2 Hz, 3 H, OCH2CH3), 2.51 (s, 3 H, ArCH3), 4.04 (q, J = 10.2 Hz, 2 H, OCH2CH3), 4.36 (t, J = 6.9 Hz, 2 H, OCH2CH2), 4.59 (t, J = 6.9 Hz, 2 H, OCH2CH2), 6.86-6.97 (m, 4 H, ArH), 7.10-7.22 (m, 4 H, ArH); IR (neat) 3446 (br), 2982 (m), 2934 (m), 2884 (m), 1591 (s), 1558 (w), 1509 (s), 1478 (s), 1454 (s), 1407 (s), 1394 (s), 1371 (s), 1354 (s), 1279 (m), 1259 (s), 1247 (s), 1217 (s), 1178 (s), 1127 (s), 1066 (s), 1043 (s), 1031 (s), 977 (s), 929 (s), 905 (s), 809 (s), 776 (m), 749 (s), 776 (m) cm-1
